Abstract

A user prompt for a diffusion model to generate an image is received. Noisy latent features generated by denoising layers of the diffusion model are collected based on the user prompt and are to generate a pre-customized version of the image. Pre-customized lighting properties of the pre-customized version of the image are predicted based on the noisy latent features. Light source properties of a light source to be logically applied to generate a customized version of the image are determined. The light source properties of the light source are applied to the pre-customized lighting properties of the pre-customized version of the image to generate customized lighting properties of the customized version of the image. A loss computed from the customized lighting properties and the pre-customized lighting properties is used to guide the diffusion model to generate the customized version of the image.
